不同直径树脂锚杆锚固性能的试验分析

Experimental Analysis of Anchoring Performance of Resin Anchor Bolts with Different Diameters

树脂锚杆是煤矿开采巷道支护中使用的重要形式,锚杆直径对锚杆锚固性能具有重要影响作用。采用试验分析的形式对三种不同直径树脂锚杆的锚固性能进行研究。结果表明,锚杆直径的增加,自身的承载性能具有明显的提升,同时锚固性能也具有较大的提升,有利于煤矿巷道的支护。在进行巷道支护设计的过程中,应适当地增加锚杆的直径,从而提高巷道的锚固效果,保证煤矿的安全开采。

Resin anchor rod is an important form of support used in coal mining roadway,and different diameters of anchor rods have different effects on the anchoring performance.The anchoring performance of three resin anchor bolts with different diameters was studied through experimental analysis.The results showed that the increase in the diameter of the anchor rod significantly improved its bearing capacity,while the anchoring performance also had a significant improvement,which was conducive to the support of coal mine tunnels.In the process of roadway support design,the diameter of the anchor rod should be appropriately increased to improve the anchoring effect of the roadway and ensure the safe mining of the coal mine.
